Permanent Bridge – Dental Treatment

Introduction –Permanent Bridge

A permanent dental bridge is a dental technique of restoration utilized for replacement of missing tooth. It adheres to contiguous teeth or other implants in a permanent manner. These bridges prevent dental problems like decay of tooth, speech disturbances and shifting teeth. There are several different types of bridges available depending upon the location of the missing teeth, the condition of the surrounding teeth and choice of the patient.

Purpose of permanent bridge:

The most essential purpose of fixing a dental bridge is for preventing the contiguous teeth from shifting in a place created by missing teeth. This shifting also causes change of bite, sore jaws and problems in the temporo-mandibular joint. Missing teeth also compromise dental and oral hygiene causing tooth decay and various gum diseases.


The bridge is anchored by the teeth on both sides of the bridge. It can also be fixed by resins or crowns to adjacent teeth. A permanent dental bridge can be made up of porcelain, metal or a combination of these materials.

There are three types of dental bridges

  1. Traditional Fixed Bridge:

Permanent bridges can last for as many as ten years or more if good oral hygiene is maintained.
This is a type in which a false tooth, also called as a pontic, is fused in between two crowns made up of porcelain material and the gap left by a missing tooth is filled. These two crowns hold onto the false tooth to the adjacent teeth on either side. This is known as a fixed bridge. By using this procedure, one or more missing teeth can be replaced. But for this procedure, the support teeth must be built up first in case if they are broken or decayed. Fixed bridges cannot be taken out of mouth like the removable partial dentures.

 Resin Bridges:

The resin bonded bridge is mostly used in case of missing front teeth. It is more cost effective.The indication for use of this bridge is when most of the teeth are healthy. The false tooth is fused with the help of metal bands which are bonded to adjacent healthy teeth called abutment teeth by resin. The amount of preparation required on the adjacent teeth is less in this type of bridge.

  1. Cantilever Bridges:

A cantilever bridge finds its use for missing front teeth where the stress is less. This permanent bridge is used when there are teeth on only one side of the open space. In this procedure, false tooth is anchored only on one side to one or more adjacent healthy teeth.


  • The dentist first prepares the teeth on either side of the defect left by a missing tooth.
  • A mild anesthetic is injected to numb the area.
  • Then the cosmetic dentist makes enough space between the teeth on either side so as to accommodate the thickness of the crown.
  • If these teeth have fillings, it can be used as a foundation for the crown.
  • The dentist makes an impression, from which the bridge, false tooth and crowns are made in a dental laboratory.
  • Until the next visit, patient is made to wear a temporary bridge.
  • This temporary bridge protects the teeth and gums till the permanent bridge is made. Or else, a Flipper appliance is used in the place of missing tooth till the permanent bridge is placed. A Flipper is a false tooth attached via either a wire or a plastic piece to the roof of the mouth awaiting the permanent bridge.
  • On the second visit, the temporary bridge is removed and new permanent bridge is fitted and checked and adjusted for any bite problems. If none, the new bridge is cemented to the teeth permanently.

Advantages of dental bridges:

  1. Bridges look natural in appearance.
  2. Generally only two visits are required for this procedure.
  3. Permanent bridges can last for as many as ten years or more if good oral hygiene is maintained.

Disadvantages of having a dental bridge:

  1. The teeth can become mildly sensitive to extreme temperatures for a few weeks after the bridge placement
  2. If proper oral hygiene is not maintained, the growth of bacteria formed from food acids on teeth and gums can become infected.
  3. Cost of the procedure must also be weighed against its advantages.
